HINGE FOR DOOR-PLATES AND OTHER STRUCTURES.

Patented May 24, 1921.;

Application filed February 9, 1920. Serial No. 357,474.

To all whom it may concern:

Be it known that I, ARTHUR O. GAYNOR, a

citizen of the United States, and a resident of Stratford, county of Fairfield, State of Connecticut, have invented certain new and useful Improvements in Hinges for Door- Plates and other Structures, of which the following is a specification.

This invention is concerned with a method of working metal and also with the product of such method.

One of the objects of the invention is to provide an article of manufacture having a hinged door or cover, as for instance a flush receptacle door, plate. which article shall be easy and inexpensive to: manufacture and which shall nevertheless be durable and ef-.

fective in use.

Another object is to provide a method of making an article of the above'type which method shall be capable of expeditious execution with relatively simple tools- Another o-bjectis to provide a hinge for an article of the type. mentioned which shall be strong, durable, inexpensive, and which shall yet not impairthe ornamental appearance of the article.

Other objects will be in part obvious and in part pointed out hereinafter.

. The invention accordingly consists in the features of construction, combination of elements,arrangementof parts, and the steps of the method whichwill be hereinafter set forth and the scope of the application of which will be "indicated in the appended claims. a i V j In the accompanying drawlngs wherein is shown one of various possible embodiments of the. several features of this invention, Figure-l is a face view of an electric flush receptacle door plate, the. cover being removed.-..

Fig. 2 isa rear view of the door plate of Fig. 1 with the cover in place.

I Fig. .3 is a. longitudinal sectional view taken along theline 3-8 of Fig. 2.

F ig..-4 .is a sectional view on an enlarged scaletaken along the line 4-4 of Fig. 2.

Fig. 5 is a plan view with parts broken away of a modified embodiment of my invention.

Similar reference characters refer to similar parts throughout the several views of the drawings 1 H Referring now to the drawings there 1s shown a flush receptacle door plate,zcoms. prising a sheet metalplate member 1, hav,. mg preferably a beveled border 2cto create; a pleasing appearance. Openings 3 for fas-:

toning members are stamped out of theplate as shown. The door of the plate as shown at 4, pref-.

I erably constitutes the piece of metal removed from the original plate member to provide the door case 5. By preferencethe door, and therefore of course its case are generally circular in shape as indicated at 6, there being preferably a rectangular ex tension 7 at the upper end, terminatinglin an upper rectilinear edge 15.

A hinge is provided for the door preferw ably comprising a hinge rod 8, passing substantially midway along the rear surface of the extension 7 of the door, said rod being,

preferably soldered at its ends as at 9 and. 10 7:5,

upon the rear of the door plate.

The loop or eye for the hinge is preferablyformed as best indicated in Fig. 4;. A, chisel or similar tool is manipulated to cut a chan.-,

nel 11 in the rear surface ofthe'door in a 8.0

direction perpendicular to the axis about which the door is to pivot, terminating adjacent said axis, The shavingwill auto-,- matically coil or curl as it is generated; and

little or no work beyond clipping off the. 86

excess length of the shaving will be required; for making the loop or'eye of propersize, and shape to lodge the hinge rod; 8', as shown .;at 13 in Fig. 4. Bypreference two.

loops are thus formed, symmetrically ar 9o ranged ad acent the sides of. the door extension 7 asbest shown in Fig. 2.

A lip 14.- semi-circular in shapeis pref erably depressed or embossed into the plate member 1 adjacent the door case 6, thislip 96 being preferably diametrically opposite the hinge. This lip as will be apparent serves not only to limit the door to its'position; within the door case but it also serves to accommodate the fingernail for purposes of 100 opening the door.

It. will be seen that contact of the surface of extension 7 againstthe rectangular upper edge 15 of the door case will limi-tthe open-p1 ing movement of the door about the hinge" rod. Thus the hinge is protecteduagainst: destruction in use which might occur if they door werefree to be opened .to an extent lim ited only b, the surface of the plate.

The met 0d of manufacturing the door plate" is to blank out the door plate member 1, the door case 6 and the holes 3 preferably in a single blanking operation and by means of a multiple die. Thereupon a forming die may be used to produce the bevel border 2 and the depressed or embossed lip 14:. The piece of metal punched out in makin the door case as above noted will serve as the door. By preference a chisel is used to make two shavings which are left attached to the door and formed into the loops or eyes 12 in the manner fully de scribed above. The hinge rod 8 is then inserted through the two loops or eyes, the door is placed into the door case in the plate with the rod 8 contacting the rear surface of the plate at its ends, and said ends are thereupon soldered in place upon the door plate, thus completing the manufacture of the article.

It will be seen that I have provided a cheap and expeditious method of manufacturing a novel flush receptacle door plate, which will be durable and effective in use. The loop or eye of the hinge is easily formed as an integral part of the article, thus dispensing with the need for making separate oop p eces and the expense and trouble of soldering, riveting or otherwise applying such elements to the door. Although the loop or eye is formed as an integral part of the door, the door itself remains imperforate and the effectiveness of the door will not be impaired either from an esthetic standpoint or with regard to its utility in keeping out dust or dirt.

Although the loop or eye is preferably formed by the method specifically set forth, it will be understood that other methods may be employed to form a loop or eye as an integral part of a plate without perforating or slitting such plate, and it is to be understood that the broader aspects of that part of my invention bearing on the article of manufacture will embrace substantially the hinge shown in Fig. 4 without regard to what method may be used for manufacturing the same.

It will also be apparent that my method of forming the shavings upon a piece of workable metal and using said shavings to,

8' is soldered to the door at 9 and the ends of the rod are embraced by loops or eyes 12 formed from shavings cut in the rear surface of the main plate member 1, thus making channels 11.

It will also be apparent that although I prefer to use two loops or eyes, a greater or lesser number may be employed. 7

Although the flush receptacle door plate shown is the preferred artioleof manufacture, it will be understood that other articles of manufacture for different purposes will be embraced Within the scope of my invention.

It will thus be seen that there is herein described apparatus and a method in which the several features of this invention are embodied, and which apparatus in its action and which method in its operation attain the various objects of the invention and are well suited to meet'the requirements of practical use.

As many changes could be made in the above construction and method and many apparently widely different embodiments of this invention could be made or executed without departing from the scope thereof, it is intended that all matter contained in the above description orshown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A sheet metal plate provided with a door or cover, cooperating hinge elements for said door, one of said hinge elements being rigid with said plate and the other rigid with said door, one of said hinge elements being disposed within the contour of and formed as an integral part of the member on which it is located, said member having a continuous integral surface adjacent to and in substantial alinement with said hinge elements.

2. A sheet metal plate provided with a door or cover, a hinge rod rigidly secured to the surface of one of said members and extending in substantial alinement there with,a hinge'eye extending about said rod, said eye being disposed within thecontour of the other of said members, and formed as an integral part ofsaid member,- said member having a continuous outer surface adjacent to saidfeye. v

3.
